The PrimeGrid project is now running a boinc project which includes the PSP project, which also includes our sieving as far as I am aware. This means we effectively have a BOINC client for SOB (sieving) which is pretty awesome if you ask me.
You can see the ranges reserved by PrimeGrid here
That's right. And you an in fact go to www.primegrid.com , get the boinc client, and get crunching. The sieving part is joint sieve for Seventeenorbust, and PrimeSierpinskiProject, so of great overall efficiency.
In something like two weeks, they found more than 1300 factors already, meaning that we eliminate about as many candidates by sieving as by LLR now.

Looking into the 2007 stats ( http://www.henleyclan.co.uk/sobsieve/2007/scores.htm )
you can see that primegrid has already reached place 14 in the yearly stats.
And that after only 2 weeks.

That is not counting the factors which have not reached the "active windows" yet. Which is worth more in points. Once it caught up with the "active window", watch it rocket to the moon.Originally Posted by ltd

Make that 5th, and looks like by tomorrow they'll have submitted the largest number of sieved factors for the year.Looking into the 2007 stats ( http://www.henleyclan.co.uk/sobsieve/2007/scores.htm )

Sieving has gone mainstream
Ah....and now we can all see that PrimeGrid is 5th. Moved to new computer - upload wasn't working.

Should keep in mind here that all the boinc users fall under the primegrid account. So all the "manual" participants would fall under another "account" to keep things in perspective. But yes, primegrid will take over as there will be more and more participants than the non-boinc crowd.Make that 5th, and looks like by tomorrow they'll have submitted the largest number of sieved factors for the year.

Joe, hopefully that should finally be sorted. And it should get updated a little more often now. Sorry that's taken so long to fix.http://www.henleyclan.co.uk/sobsieve...ded_marked.zip still has not been uploaded.
PrimeGrid is now 4th and still moving, place bets now on when it will take 1st!
Not this year. Should take 2nd for the year, and then I guess will lock out the 2008 stats.
In the all time stats http://www.henleyclan.co.uk/sobsieve/alltime/scores.htm a lowly 56th and a long way to go.
So the current standings are:Will this be the standings at years end? or will Primegrid move up to 2nd? or even 1st?1 engracio

It's good to see you guys utilizing the boinc platform to sieve. I thought our success over at Riesel Sieve would catch your attention sometime. We are closing in on 5P and almost 4P of that is boinc sieve. Since we still have 66 k values left...it would have taken forever to sieve to this depth without boinc. Currently we are down to just 14T/day as we are moving more focus to LLR.
Ride the boinc sieve wave as long as you can. As long as those factors keep falling out...I'd ride that pony until it died.
Good luck and see you at the prime race finish line.

PrimeGrid is #1 for this year in sieving and has reached position #6 over all time - not bad!
Sieve really going strong with bionic and the manual ranges.
PSP just eliminated a k so that should speed things up a touch as well. On wards and upwards. It's possible to beat riesel in sieve since our dat is smaller we would just need more people.
Should all sieving now be done with the PSP Boinc client?
Because I see very little activity here.
And one of the reasons for me to start sieving is to lift the place of the Dutch Power Cows in sieving. But since I have to send in the results to both SoB sieving and PSP, will I have to register at both sites, and be getting points on both projects or how will that work?
Thanks for the information.
Manual sieving is still continuing.
You can think of combined sieving as operating in two sieve projects at once, it makes more efficient use of your processing power than sieving in the different projects seperately.
If you have a 24/7 internet connection, I guess BOINC is your choice. You will get BOINC credit.
If you have more of a standalone-PC, you should prefer manual sieving. If you are concerned about credit, you need in this case to get a username for the semiautomatic reservation system, for PSP (post a message in the mersenneforum-->PSP-->join-a-team thread), and at SoB (forgot how that works). You will submit factors at PSP, at SoB, and get separate credit.
Did that help? H.

Sievers of all projects unite! You have nothing to lose but some PRP-residues.
Yes that did help.
So the BOINc client only gives BOINC credit. And doing it manually gives credit to both projects.
Right?
And since I am doing this to help DPC getting up in the DC vault, I'll go with the manual sieving then.
Thanks for the info!
Well, actually, there might still be confusion, as there are two kinds of credits at SoB. A compendium of all the different kinds of credit:
http://www.seventeenorbust.com/stats/teams/ ; here the DuchPowerCows are indeed doing fairly well; these are the stats for PRP-Tests, i.e. running the normal SoB-Client that you get here:
http://www.seventeenorbust.com/download
The SoB-sieving-stats look like this: http://www.henleyclan.co.uk/sobsieve/2007/scores.htm ; here I don't see any notion of team whatsoever. This one is the credit I referred to in my above post.
The PSP-sieving credit can be seen here: http://www.psp-project.de/stats.html ; the Power Cows have not yet shown particular interest for neither of the two sieving- and PRP-parts.
And concerning Primegrid, they score a mere rank 62 here: http://www.primegrid.com/top_teams.php ; being passed by even by third world countries like Canada and ... Belgium.
BUT: Sieving is the most efficient to bring the whole two projects further, and the gentlemen's choice, if you ask me.
Do whatever pleases you most. But one request: if you allready reserved a manual sieve range, please finish it, as not doing so causes manual work, I guess.
Cheers, H.

You call a number one position doing fairly well?
But this was not what I want to do, because this is what I am doing at the moment, because the Dutch Power Cows are on a stampede there.
I am looking ahead to find something to do afterwards.
Actually in the teams I do see:
9 Dutch_Power_Cows 943315.34 ( 0.30) 0 ( 1 ) 0 ( 1 ) 1 0 0 0 189/289
However we are not in this:
http://www.henleyclan.co.uk/sobsieve/2008/scores_t.htm
But with manual sieving I will be sending in results for both the SoB sieving and the PSP-sieving? right?
Well, that might be another thing for the future then
I haven't reserver anything yet, I am planning the switch to manual sieving in a week or so. After the Stampede has finished and the tests of the normal SoB are completed.
I hope that I now understand things correctly.
To get the most credit out of manual sieving, yes, you need to submit your factors at
http://www.seventeenorbust.com/sieve (don't forget to log in)
and
http://www.psp-project.de/sieveimport.php (check "Sob factors reported by user"; you need to drop a message in the "Join a team"-thread so that he can affect you to your team)

This is probably because the team has not submitted any factors yet this year?Actually in the teams I do see:
9 Dutch_Power_Cows 943315.34 ( 0.30) 0 ( 1 ) 0 ( 1 ) 1 0 0 0 189/289
However we are not in this:
http://www.henleyclan.co.uk/sobsieve/2008/scores_t.htm
If you look at http://www.henleyclan.co.uk/sobsieve...e/scores_t.htm you will see the all time stats for the team.
I know that DPC wasn't in the rankings because they submitted no results. Well, know... I thought so.
That is why I am going to do it as a member of DPC. Just to get them active in a somewhat smaller project.
And who knows, maybe others DPC'ers find their way here as well.
If you want to do some good to SoB, and the fame of the DPC, you direct as many people as possible to Primegrid, crunching PSP/SoB joint work.
The reasons:
- sieving helps Sob even more than doing PRP tests;
- becoming number 1 should not be so difficult over there.
- everything is automatic, and easy, hence suited for a big crowd of people
- it is easier to manage new BOINC member for the admins than 50 new manual sieving members
- I think the manual sieving stats are somehow obsolete after the enormous success of the BOINC sieving revolution. (See Primgrid is already the number 2 all time user?)

just one more question, where do I register my username and team for the psp project?
For manual sieving you should post on the PSP forum on this thread ( http://www.mersenneforum.org/showthread.php?t=8162 ) to get your username added to the factor submission form. You can then post on this thread ( http://www.mersenneforum.org/showthread.php?t=2692 ) to join a team.
OK, me again.
I just completed sieving of a range:
The reserved range was:
12303000G - 12303100G
I ran this command (on linux):
./sr2sieve -s -p 12303000000000000 -P 12303100000000000 --intel
And the result on screen was:
sr2sieve 1.7.9 -- A sieve for multiple sequences k*b^n+/-1 and b^n+/-k.
Read 1963642 terms for 16 sequences from dat format file `SoB.dat'.
Split 16 base 2 sequences into 160 base 2^360 subsequences.
Expecting to find factors for about 0.43 terms in this range.
sr2sieve 1.7.9 started: 991 <= n <= 49999997, 12303000000000000 <= p <= 12303100000000000
p=12303099997319357, 671093 p/sec, 0 factors, 100.0% done, ETA 15 May 04:07
sr2sieve 1.7.9 stopped: at p=12303100000000000 because range is complete.
What do I need to put into the form to send in the results?
OK, from what I have read so far, there is no factor found, so I have nothing to submit.
Because if it does find a factor, there would have been a factors.txt and this content I need to submit, right?
But How do I let you guys know that there is no factor to be found in this range?
Last edited by balachmar; 05-15-2008 at 03:52 AM. Reason: new information found
When you edit your range to mark it finished, put 0 in the Factors Found.
Joe O
Do I need to let PSP sieve know as well?
Or do you only get points for factors you have found?
No. That's right. At PSP, instantly; and for SoB factors only, when First(orSecond-)Pass passes them (makes use of them (to eliminate a candidate). (You get a little bit of credit, but the most is to come later).
(Remember someone could find a prime for that k, and then we wouldn't continue at all do LLR on your number).
Hope that makes sense... Yours H.

But do I have to send something in to the psp website?
I am doing manual sieving. And I didn't find a factor. So I don't know what I would be supposed to send in.
The manual sieving website is the only place where you need to reserve a range and mark it is complete. In the event that you find factors you should submit them to both PSP and SoB seperately.
Hi guys. I need a team in psp sieve. I'm currntly in 35 place, but have no team ((
My team called Ukraine (as usual).
How can I have one?
wbr, Me. Dead J. Dona \
Death, you are alive!
I posted here

that should take care of it. H.

I fear I am not getting in the SoB Sieve stats.
With sending in the result at SoB I get:
Factor table setup returned 1
Test table setup returned 1
0 of 1 verified in 0.02 secs.
0 of the results were new results and saved to the database.
and from PSP I get:
User: balachmar **SOB Flag: PSP_Only
Input contained 1 total lines.
Input contained 1 valid lines.
Input contained 1 valid lines from PSP k values.
Input contained 0 valid lines from SOB k values.
Input contained 0 invalid lines.
Input contained 0 lines with unknown K.
Input contained 0 lines with already known factor.
Input contained 0 wrong factors.
Am I sieving in the wrong range or what?
